I would also be taking a real hard look at all the other screwed in ladder supports.
I am going to look at that this weekend while we're at an RV park but I'm leaning toward the strongback/through bolt fix, the pantry is in that corner so should not be a problem. But does anyone know what is actually in these walls? Is it rigid board insulation between studs?
